'CALLING DEVICE Filed Sept. 25, 1929 Patented Dec. 15, 1931 UNITED STATES PATENT oFFIcE HERBERT F. OBERGFELL, OF RIVER FOREST, ILLINOIS, ASSIGNOR TO lRESERVE HOLD- ING COMPANY, OF KANSAS CITY, MISSOURI, A CORPORATION OF DELAWARE CALLING DEVICE Application led September 26, 1929. Serial No. 395,239.

The present invention relates in general to calling devices, but more particularly to the provision of means for protecting the mechanism of a calling device, of the general type of that disclosed in Obergfell Patent No. 1,642,822, issued September 20, 1927, against being damaged as a result of water being splashed thereon. The provision of such means is highly desirable when such calling devices are used on ship decks, or other places where they are not fully protected against adverse weather conditions.

The invention is disclosed in a single sheet of drawings which illustrate the invention applied to a calling device of the type disclosed in the patent hereinbefore referred to, only those parts of the calling device being shown which are considered necessary to clearly illustrate the invention.

In the drawings Fig. 1 is a plan view of a calling device, Fig. 2 is a perspective view of the protecting cover; while Fig. 3 is a sectional view in elevation taken on line 3-3.

Referring now particularly to Fig. 3 the assembly of the protecting cover into the calling device will be described. The main support for the mechanism of the calling device comprises the usual eup- 25 having a. ledge in its upper edge for receiving a number plate 15. This number plate, in the present case, is made of bakelite and is held in place by the free ends 26 and 26 of a spring member se-,

cured to the base of the cup 25. The spring members fit into notches existing in the upper edge of the upwardly extending portion of the number plate 15. In the calling devise of the patent hereinbefore referred to the finger hold dial was secured to a plate corresponding to 18, with a shaft 20 for operating the mechanism of the device7 by means of a screw such as 9.

In accordance with the present invention, however, intermediate to the dial 10 and plate 18 is placed the protective cover 5, the downwardly extending wall of which closely surrounds the upwardly extending portion 81 of the number plate 15. In order to avoid any danger of the bottom of the cover rubbing on the number plate 15, which might otherwise occur when pressure is applied du r-y the dialling operation, this latter plate is provided with a depression 3. V

In all uses of the dial the same is mounted on a slant or in a vertical position, and, any water splashed thereon will readily 4be deflected by the cover 5 and will run off the number plate 15. Y

What is claimed is:

l. In 'acalling device for use at a subscribers station of an automatic telephone system, a finger hold dial, a number plate having an opening therein through which the operating mechanism of the dial connects with said finger hold dial, and a cover for the opening of said plate, comprising an inverted shallow cup having its base adja cent the bottom side of said dial and its walls extending down over an upwardly extending portion of said plate.

2. In a calling device for use at a subscribers station of an automatic telephone system, a circular number plate having an upwardly extending circular walled opening therein and also having a narrow depression in its surface adjacent to and surrounding the wall thereof; and a cover for said opening, in movable relation thereto, comprising an inverted circular shallow cup the wall of which telescopes over the wall and depressed portion of said plate.

3. In a calling device for use at a subscrihers station of an automatic telephone system, a cup-like support, mechanism within said support, a number plate, a finger hold dial, and a cover for preventing the entrance of liquids into said support located intermediate to said number plate and dial and movable with respect to said number plate.

4. In a calling device for use at a subscribers station of an automatic telephone system, a cup-like support, a finger hold dial, mechanism within said support having an upwardly extending portion for connection with said dial; a number plate partially closing the top of said support, and having a conl tinuous upwardly extending wall surrounding the upwardly extending portion of said mechanism; and an inverted shallow cup, placed between said finger hold dial and the upwardly extending portion of said mechanism, with its wall surrounding that of the number plate to prevent liquids splashed upon said plate or dial entering the support and damaging the mechanism within it.

5. In a calling device for use at a subscribers station of an automatic telephone system, a cup-like support, mechanism within said support, a linger hold dial for operating said mechanism, a number plate partially enclosing the top of saidsupport and having a continuous upwardly extending wall surrounded by a depressed portion, and an inverted shallow cup placed intermediate to said dial and number plate and having its wall portion extending down over the upwardly extending and the depressed portions of said number plate to a level coinciding with the level of that portion of the number plate adjacent the outer edge of the depression therein.

In witness whereof, I hereunto subscribev my name this 23rd day of September, A. D.
